LS75C2D-T Equivalent & Substitute Parts

Part Overview

The LS75C2D-T is a tactile switch manufactured by Citizen, classified as SPST-NO (Single Pole Single Throw - Normally Open) with a contact rating of 0.02A at 12VDC. This component features top actuated surface mount design with a 0.50mm actuator height and 0.15mm switch travel. The LS75C2D-T is designated as obsolete product status, necessitating identification of active equivalent components to maintain design continuity and ensure supply chain availability for new production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LS75C2D-T is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (Momentary)
• Contact rating: 0.02A @ 12VDC

Mechanical Compatibility:

• Mounting type: Surface Mount (SMD)
• Actuator orientation: Top Actuated
• Actuator height: 0.50mm
• Outline dimensions: 2.80mm x 1.90mm
• Switch travel: 0.15mm
• Termination style: SMD (SMT) Tab

Regulatory & Environmental:

• RoHS compliance status
• Moisture Sensitivity Level: MSL 1

The substitute part LS75C2D7 maintains equivalence across all critical electrical and mechanical parameters while offering active product status and enhanced environmental protection specifications.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement:

The LS75C2D7 is the direct active equivalent for the obsolete LS75C2D-T. Both components share identical electrical specifications (SPST-NO, 0.02A @ 12VDC), mechanical dimensions (2.80mm x 1.90mm outline, 0.50mm actuator height), and functional characteristics (momentary operation, 0.15mm travel, 300,000 cycle mechanical life).

Compliance Considerations:

The LS75C2D7 provides enhanced regulatory compliance through ROHS3 certification compared to the RoHS Compliant status of the main part. Both components maintain MSL 1 moisture sensitivity rating and EAR99 export classification.

Environmental Protection Enhancement:

The LS75C2D7 incorporates IP67 ingress protection (dust tight, waterproof), providing superior environmental sealing compared to the main part. This enhancement does not affect electrical or mechanical compatibility and represents a functional improvement for applications requiring moisture resistance.

Packaging Transition:

The substitute part transitions from Cut Tape (CT) & Digi-Reel® packaging to standard Tape & Reel (TR) format. This packaging change aligns with current manufacturing standards and does not affect component performance or PCB assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can LS75C2D7 directly replace LS75C2D-T in existing designs?

A: Yes. The LS75C2D7 maintains electrical equivalence (SPST-NO, 0.02A @ 12VDC), identical mechanical dimensions (2.80mm x 1.90mm), and matching actuator specifications (0.50mm height, 0.15mm travel, top actuated). PCB footprints and assembly processes require no modification.

Q: What is the difference in operating force between the two parts?

A: The LS75C2D-T specifies 160gf operating force, while the LS75C2D7 specifies 163gf. This 3gf variance falls within normal manufacturing tolerance for tactile switches and does not affect functional compatibility or user perception of actuation feel.

Q: Does the IP67 rating on LS75C2D7 affect compatibility?

A: No. The IP67 ingress protection specification on the LS75C2D7 represents an enhancement that provides additional environmental sealing. This specification does not introduce incompatibility and is beneficial for applications exposed to moisture or dust.

Q: Are there packaging considerations when transitioning from LS75C2D-T to LS75C2D7?

A: The main part uses Cut Tape (CT) & Digi-Reel® packaging, while the substitute uses standard Tape & Reel (TR) format. Both packaging formats are compatible with standard SMD assembly equipment. Reel specifications and tape dimensions follow industry standards for 8mm tape width components.

Q: What is the regulatory status difference between RoHS Compliant and ROHS3 Compliant?

A: ROHS3 represents the current revision of the RoHS Directive with updated substance restrictions. The LS75C2D7 meets the latest regulatory requirements, ensuring compliance with current and future procurement standards. Both parts are lead-free and meet hazardous substance restrictions.

Q: Are both parts suitable for the same voltage and current applications?

A: Yes. Both components are rated for 0.02A @ 12VDC contact rating. Circuit design and application requirements remain unchanged when substituting LS75C2D7 for LS75C2D-T.

Q: What is the mechanical life expectancy for both parts?

A: Both the LS75C2D-T and LS75C2D7 are rated for 300,000 mechanical cycles, providing equivalent durability and service life expectations.
